[364-2] Drifting Ice Stations, 2016Since the first such expedition in 1893, manned ships have been deliberately frozen in drift ice to study conditions in the Arctic Ocean. Six ice drift missions are detailed twice, once in scale and then enlarged, transforming the Northern Hemisphere into the Arctic Circle. The Tara Expedition is the most recent; in 2009 it ended a two year drift studying climate change in the Arctic.
